We introduce a new approach to model the market smile for inflation-linked derivatives by defining the Quadratic Gaussian Year-on-Year inflation model -- the QGY model. We directly define the model in terms of a year-on-year ratio of the inflation index on a discrete tenor structure, which,...

Unlike tranches of synthetic CDOs, that depend only on the defaults of the underlying securities, tranches of cashflow CDOs also depend on the interest cash flows from the coupons of the securities. Whilst fast, accurate, (semi-)analytic methods exist for pricing synthetic CDO tranches (Hull and...

This work extends the contagion model introduced by Nier et al. (2007) to inhomogeneous networks. We preserve the convenient description of a financial system by a sparsely parameterized random graph but add several relevant inhomogeneities, namely well-connected banks, financial institutions...

This paper aims to investigate the main determinants of Tunisian bank stability. To achieve this goal; we have used a dataset of ten (10) Tunisian banks during the period 1990-2015. These banks are the most dynamic and the most involved in the financing of the economy. The econometric strategy...

We develop an agent based model of traditional banks and asset managers. Our aim is to investigate the channels of contagion of shocks to asset prices within and between the two financial sectors, including the effects of fire sales and their impact on financial institutions' balance sheets. We...

This paper offers a means to enhance the efficiency of the financial system in the form of Participating Mortgages (PMs) to make it more resilient and to mitigate systemic risk. We establish a basic setup to study the variants of PMs, distinguish them from convertible mortgages and derive...
